Deleting Reusable Blocks

Hi there.

I am using Gutenberg Reusable blocks to design posts for my amazon affiliate website.

I have used that block in many posts.

Now, I have created a new block.

What if I delete that previous reusable block?

When I try to delete it, it says: “Are you sure you want to delete this reusable block?

It will be permanently removed from all posts and pages that use it.”

Since I have used that block by converting it into regular block. Still, it will affect?

Thanks
